So I'm doing an outdoor grow and looks like one plant is starting to flower.

I have two ferts, one is Advanced Hydroponics 10-7-18 and Botanicare 3-1.5-4. 1 tsp of AH seems to be the veg dose and 1 tbsp of the Botan the veg dose per gallon. So if I cut each of those to 25% of the veg dose am I giving changing the effective nute strength to 2.5-1.75-4.5, and 1.5-.75-2 respectively? As I understand ppm, that's what I'm doing.. is that right? And is that to say that if I doubled those veg doses I'm making it 20-14-18, and 6-3-8?

I'm just trying to figure out how much to decrease my veg ferts and how to add a phosphorus source with it.

I use Advanced Nutrients and I grow both hydroponically and in soil. I use the grow-micro-bloom 3 part nute system from AN. The NPK ratios are as follow: Micro: 5-0-1, Grow: 2-1-6, Bloom: 0-5-4. I use them in a 1:1:1 ratio, starting with 0.77 tsps per gallon during the seedling/clone stage. I increase the dosage each week: 1.54 (in the vegetative stage), 1.40 (mild flowering), 1.74, 2.07, 2.56, 3.20, and 3.84 (aggressive flowering) in PPM, this is 600, 950, 1000, 1200, 1400, 1600, 1800, and 2000. Your soil's ph should be betwen 6.2 and 6.4. Flush with plain water for 1-2 weeks before harvesting. Hope this helps. Happy harvests!

does superthrive work?
